[openstack-dev] [neutron][lbaas][octavia] what are the main differences between the two

You’re definitely stuck on lbaas v1 until you upgrade to Kilo, but…

But, it would be possible to write an lbaasv1 driver for octavia, though octavia likely won’t be mature enough to be useful for that until the end of Liberty or so. Also, though “vendor” is a bad word in openstack (and that’s ok), there are a few vendor offerings, some of which will make v1 more usable and/or extend it with other features.

Can you describe what you’re trying to do, and we can make some suggestions?  Worst case, we’re always looking to hear more use cases as we build things.

Thanks,
doug

It re-organizes the objects, and adds TLS termination support, and has L7 plus other new goodies planned in Liberty. It similarly has an haproxy reference backend with a few vendors supporting it.

It is expected to be the reference backend implementation for neutron lbaasv2 in liberty. It could also be used as its own front-end, and/or given drivers to be a load balancing framework completely outside neutron/nova, though that is not the present direction of development.
